Effective prediction and analysis of winding temperature rise and hot spot temperature is an important prerequi-site for safe and stable operation of dry-type transformers.The present work conducted the simulation of temperature field distribution of an 8000 kVA dry-type transformer under forced air cooling conditions,and verified validity of the simula-tion results by AF test.On this basis,it studied the influences of model simplification method and structural optimization design on temperature rise simulation results,and carried out error analysis.The results indicated that the current numer-ical simulation method can effectively predict transformer's temperature distribution and may provide reference for design,optimization and evaluation of similar types of transformers.
